EDWIN HUDSON, OF IPAVA, ILLINOIS, ASSIGNOR OF ONE-THIRD TO HENRY A. DUFIELID, OF GLASFOR-D, ILLINOIS. AND ONE-THIRD T0 FRANK F. I-IODSON, OF

KINGSTON MINES, ILLINOIS,

W'A'IER-ELEVATING MECHANISM.

To all whom it may concern:

Be it known that I. EDWIN Henson, citizen of the United States, residing at Ipava. in the county of Fulton and State of Illinois. have invented certain new and useful Improvements in ater-Elevating Mechanism; and I do hereby declare that the following is a full. clear, and exact description of the invention. which will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a water elevating device adapted for use in deep wells and the like.

The invention pertains more particularly to a device comprising receptacles for water under air pressure to be elevated and delivered to any desired source.

The object of the invention is to simplify devices of this kind by producing a simple structure whose parts are not likely to get out of order.

To the end that the invention may be understood I have provided the accompanying drawing. in which.

Figure 1 is a sectional elevation of a water elevating device involving my invention the same being shown submerged in a well. Fig. 2 is a device for engaging a valve and float rod shown in perspective. Fig. 3 is a sectional elevation of a part of what is shown in Fig. 1 including a valve and valvcrod. Fig. a is a plan of part of what is shown in Fig. 3. Fig. 5 is a plan of a valve.

A indicates the wall of a well or other place from which water is to be elevated. and B and C are two receptacles adapted to receive both air and water. The receptacles may be suitably suspended in the well, or they may rest upon the bottom of the same. However, the manner of support is not shown since it t'orms no part of the invention.

I) is a cylinder having position above the tanks B C communicating with them through pipe connections E F respectively. Mounted on the top of said cylinder is a valve chamber G with which is connected a pipe H. for introducingair thereto. J is a slide valve within said chamber and this rests upon the top of the cylinder and is adapted to cover either of two ports K I. in the wall of said cylinder. In the valve chamber near each end is pivoted a bell- Specification of Letters Patent.

crank M, N, in any suitable manner. One end of each bell crank has control of the valve J through valve stems C), P, for example. extending "from the ends of said valve. said stems extending through the arms of the bell-crank. For example the latter may be slotted (not shown) whereby they may move without binding upon the said valve stems.

Q is a float-rod suspended from one of the arms of the bell-crank M and depending into the receptacle B, and R- is a fl0at-rod suspended from the free arm of the'bellcrank N and depending into the receptacle C.

S is a float slidable upon the valve rod Q, and T is a float slidable upon the valve rod R.

U and V are pipe sections mounted upon the top of the receptacles B and 0 respectively, both comnuinieating therewith. In Fig. 3 one of these pipe sections, V for example, is shown on a much larger scale.

\V is a diaphragm through which a valverod 2 extends and adapted to move vertically, said diaphragm being provided with openings 3, for example, between cross arms 3 of said diaphragm. 4t is a valve carried by the rod 2 and provided with apertures 5 correspcmling in position to the said cross arms 5 ot the diaphragm \V so that when the valve lies against the underside of the said diaphragm the apertures will be closed by said cross arms.

livotcd at one end within the receptacle B is a float arm b and connected with this in a pivotal manner is a valve rod 7 corresponding to the valve rod 2 in Fig. 1. 8 is a float suspended from said float arm 6, and 9 is a suitable stop for limiting the downward movement ot' the float arm.

in the receptacle C, 10 is a float-arm corresponding to the float arm (3, the valve rod 2 being attached to it. 11 is a float corresponding to the float 8, and 12 is a limiting member corresponding to the member 9 described.

\Yithin the cylinder D is a piston 13 in control of a piston rod 14. extending in opposite directions through the ends of said cylinder 1) each end having secured thereto a part to. Fig. 3. provided with a forked extremity 16 adapted to engage beneath the head 17 upon the valve stems 2, 7 The said cylinder D is provided withstufling boxes 18 through which the piston rod 1A extends and these prevent leakage of air from said cylinder.

19 is a branch pipe connected into the bottom of each receptacle B G for the discharge of water.

B and C are foot valves or check valves in the bottom of the receptacles B C respec' tively.

In operation one of the tanks, for instance the tank B, may be considered full of water. Air under pressure within the valve chamber G is introduced into said receptacle through the port K of the cylinder D and the pipe E, forcing the water in said receptacle B through the branch pipe 19 the discharge of Water continuing while the air pressure is upon the water. It is observed in Fig. 1 that the float 8 is in its raised position and in consequence the valve in the pipe U, the construction of which has been described, and is shown in Fig. 3, is consequently closed. The float and valve are therefore in their highest positions and are held by the forked extremity 16 of the member 15 and therefore the float as the water level fillsdue to discharge through the pipe 19 cannot descend but remains suspended. The float S, however, falls with the Water level until it reaches and rests upon a foot piece Q at the lower end of the valve rod Q. As this takes place and the water still continues to descend the weight of the float draws the valve rod Q, down and moves the valve J through the bell-crank lever M toward the left and covers the port K and simultaneously uncovers the port L as will be seen in the dotted lines. As this occurs the passage to the receptacle B is interrupted and pressure placed upon the water in the receptacle 0. The air in the receptacle B must now be liberated to permit water to enter through the check-valve or foot-valve B. The air under pressure in the valve chamber in passing into the cylinder D through the port L enters the receptacle C and at once discharges water through the branch pipe 19 it being understood, however, that at such times the valve 4 will be closed, but which valve, for the purpose of description herein, is shown open. As air pressure is under pressure in the receptacle C it must act upon the piston 13 forcing it to the left as viewed in Fig. 1. This releases the float-rod 7 so that the float will fall and thus open the valve in the pipe U. Bythus opening the valve in said pipe U the air is permitted to escape and the water will therefore lift the valve B and rise within the receptacle B gradually forcing the air out through said pipe U. The level upon reaching the float 8 will raise that member in position so that the rod will be engaged by the forked extremity 16 of the piston-rod 14, the parts being then in position ready for the introduction of air upon the water.

The receptacle C, as shown in Fig. l, is receiving water, the float 11 being in the act of rising to carry the head 17 of the valve rod 2 into the path of the forked extension 16, the valve C of course, being raised to admit water. It is to be understood that the receptacles in practice are alternately fllled and emptied rather than that both are full of water as indicated, it having already been stated that this drawing shows the relation of the parts merely for descriptive purposes. When one receptacle is just about empty the other is nearly or quite filled so that the instant the float on the valve rod Q or It of an empty receptacle, is allowed to shift the valve J air pressure is at once placed upon a full receptacle.

My device is really quite simple and very effective in operation. It is simple because it requires but few parts without any complications whatever.

I desire to state that slight changes may Y be made without departing from the spirit of the invention, or the appended claims, and

Having thus described my invention, I claim 1. In an apparatus for elevating liquids, the combination of a pair of receptacles each including a discharge opening for water, and each also including, a valve for the inflow of water, a conduit forintroducing air under pressure into either of the receptacles, a float controlled valve for directing air under pressure into one of the receptacles and for simultaneously interrupting the flow of air to the other receptacle, there being an opening for air leading from each said receptacle, a float-controlled valve for each opening, and a piston including a separate part adapted to automatically engage and hold one of the last named valves in its closed position.

2. In an apparatus for elevating water, the combination of a pair of submerged receptacles adapted for receiving water, and air under pressure, a conduit for the introduction of air into each, avalve adapted for directing the air alternately into one and then into the other of the receptacles, a float in each receptacle each adapted to control said valve, there being an air escapeopening leading from each receptacle, a valve in control of each opening, a float in control of each valve, and means adapted to alternately and automatically hold either valve closed.

3. In an apparatus for elevating water, the combination of a pair of submerged twin receptacles each including a discharge opening for water and a valve for the inflow of water to each said receptacle, means through which to introduce air under pressure alternately into the receptacles including a valve, a rod in control of each valve and depending into each receptacle, each said rod including a stop portion in its lower end, a separate float adapted to move relatively to the rod and to engage the stop thereon, there 5 being an opening in the upper portion of each receptacle, a separate valve in control of each valve, and means controlled by air pressure for holding either of the valves in its closed position.

10 l. In a Water elevating mechanism, the combination of submerged twin receptacles adapted to receive water and including check valves in their lower portions and each having a place of discharge for water, a

1-5 receptacle for air communicating With each of said receptacles and includin two ports, a valve adapted for alternatey covering one and exposing the other of the ports, a

conduit adapted for introducing air through either of the ports, a member in each of the 20 said twin receptacles and each adapted to impart movement to said valve and each including a float, an escape opening in the upper portion of said twin receptacles, a valve in control of each including a valve 5 stem, a separate float in control of each valve, and a piston within the air receptacle including a separate part to engage one of the valve stems.
